Abstract
An electrode plate manufacturing apparatus for a secondary battery includes a supply reel configured to supply a substrate, the substrate having a first surface that is uncoated and a second surface that is at least partially coated, and a patterner adjacent to the supply reel, the patterner including a polygon roller and a support roller facing each other, the patterner being configured to pattern the substrate passing between the polygon roller and the support roller, and the polygon roller including convex curved portions that extend in an axial direction of the polygon roller and that are arranged in a circumferential direction of the polygon roller.

An electrode plate manufacturing apparatus for a secondary battery, the apparatus comprising:
- a supply reel configured to supply a substrate, the substrate having a first surface that is uncoated and a second surface that is at least partially coated;
- and
- a patterner adjacent to the supply reel, the patterner including a polygon roller and a support roller facing each other, the patterner being configured to pattern the substrate passing between the polygon roller and the support roller, and the polygon roller including convex curved portions that extend in an axial direction of the polygon roller and that are arranged in a circumferential direction of the polygon roller.
An electrode plate manufacturing method for a secondary battery, the method comprising:
- supplying a substrate having a first surface that is uncoated and a second surface that is at least partially coated;
- and
- forming a pattern on the substrate by passing the substrate between a polygon roller, on which a plurality of convex curved portions are formed, and a support roller, while pressurizing the substrate,
- wherein the convex curved portions extend in an axial direction of the polygon roller and are arranged in a circumferential direction of the polygon roller.
